APPARATUS FOR MOISTENING YARNS.

To aZZ w/z.0m it may concern: Be it known that I, PAUL SGHILDE, a sub- ]ect of the Emperor of Germany, residing at Seilerweg A26, Hersfeld, Hessen-Nassau, a

Province of Prussia, Germany, engineer, have invented certain new and useful Improvements in Apparatus for Moistening Yarns, of which the following is a specification.

The object of this invention is to produce apparatus adapted to impart a certain percentage of moisture to yarns etc. made in the yarn factories. As a matter of fact these yarns leave the looms and the warm spinning rooms in a dry state and consequently have a great inclination to form loops, get entangled, or get into knots, thus rendering further manufacture, weaving etc. very difficult. It is furthermore of advantage to and facilitates business if the yarns contain a certain agreed upon and adhered to erhitherto factory owners have tried in vain by various means to obtain and maintain this degree of moisture in their yarns. Especially with yarns on spools (cops, cross-wound bobbins etc.) it is difficult to quite evenly moisten the yarn and the present invention will entirely do away with this-disadvantage. In the accompa-n ing drawings Figure 1 is a partly sectional elevation, and Fig. 2 is a ground plan of my yarn moistening apparatus.

The apparatus hereinafter described and specified comprises a chamber or shaft into which finely distributed or evaporated water is forced by means of a strong current of a r, which may be warmed or heated previously as circumstances require. In the chamber or shaft there are a number of trays to receive the yarns to be treated. These trays consist of open frames, or they have bottoms made of wire netting or the like, and the baskets ave sides and bottoms which are perforated or made of open wirework of suitable mesh. The moistened air of necessity is forced through the cops or bobbins lying in the baskets and during its passage therethrough gives up a part of its moisture to the yarns. Thereafter the air is sucked 0E from the chamber, the apparatus being so constructed as to regularly alter the direction of the ourair, 71. e. to send same alternately up and down the chamber or shaft.

ratus being subjected for the baskets which contain Serial N 9. 405,974.

ng chamber or shaft 1 consists of a closed iron frame, inside which the trays 2 are arranged so as to be moved up and down.

For technical reasons the downward movement is generally chosen. Adjacent to the chamber or sha t or, in case of more important installations,between two chambers or shafts, there is a lift 3 with a hoist by means of which the trays 2 are separately lifted or let down, as the case may be, by mechanism which forms no part ,of the present invention.

If the trays 2 inside the chamber or shaft 1 are moving downward (which will be generally the case) those inside the lift will move upward and vice versa. The construc- Patented Apr. 12, 1910.

tion of the apparatus is such as to permit of the mechanical movement at any time of the lowermost tray in the moistening chamber or shaft 1 from said shaft into the lift The whole remaining column of trays afterward descends the top. The tray taken out from the bottom is then dischar ed and filled again with baskets containing fresh dry yarns, and then hoisted up by the lift 3 to the top of the shaft 1 to be there placed uppermost on the column of trays 2 therein. The lift 3 descends again and the whole operation may be repeated. Of course there must be suitable intervals between the emptying of the bottom trays to allow of the yarns in the appaperiod to the moistening process, generally speaking for several hours. The apparatus consists further of an air fan 4:, and a water distributer or evaporator 5, also, if necessary or desired, of an apparatus or arrangement for warming or heating the air, and finally of connecting tubes.

The water distributer or evaporator 5 may be constructed after any of the well known patterns. The steam is absorbed by the current of air'while the same passes above the evaporator. The warming or heat1ngapparatus may also be suitably constructed or it may be omitted altogether.

The air fan 4 sucks up the air from the heating apparatus, or from the surrounding atmosphere, forces it through the distributer or evaporator 5 and then through atube 7 leading to the bottom of the moistemng chamber or shaft 1 through which 1tis subsequently driven. The air after having lost its moisture while traveling through the inside the chamber or. shaft, thus making room for a new tray at a sufficiently long chamber or shaft 1 escapes into the open, or is conducted through a pipe 8 either to the heating apparatus 6 or dirwt to the inlet of the fan. It is possible to reverse the current of air by opening (while the air is being sucked from the chamber or shaft 1) the branch air pipe or tube 9 hitherto closed. The air then first passes into the heating apparatus 0, thence through the fan 4, through the distributer or evaporator 5, and then through a second branch pipe 10, which was hitherto'closed, into the pipe 8 ascending to and leading into the top part of the chamber or shaft 1. The closing of the various connecting tubes is effected by means of flap, or other, valves which can be operated from the outside, so as to open communication for the air in either direction, The pipe 8 is provided at a point below its junction with the pipe 10, with a valve 11. The pipe 9 is provided with a valve12; the pipe 7, with a valve 13 and the pipe 10 with a valve 14. With this arrangement, it will be seen that when air flows through the pipe 7, upwardly through the shaft 1 and returns through the pipe 8, the valves 13 and 11 are opened and the valves 12 and 14 closed. \Vhen the direction of the air current is reversed, the valves 11 and 13 are closed and the valves 12 and 14 are opened. In such a case the air will pass through the moistener 5, the pipes 10 and 8, downwardly through the shaft 1, being returned by the pipes 7 and 9 and the heater 6. By taking advantage of this arrangement, viz., forcing the moist air into the shaft alternately from above and from below, the result aimed at to subject all the yarns evenly and equally to the influence of the air and thereby imparting to them an equal degree of moisture throughout, is most effectually attained.

A single moistening installation composed of a fan, evaporator or distributer, with the necessary tubing and flaps or valves, may feed a number of moistening shafts, and several shafts may be arranged in such a manner as to necessitate only one lift.
